The short answer

Not much yet. Low weekly doses appear reasonably safe over a year, with only hints of benefit.

An earlier set of studies found that a related drug improved older adults’ response to the flu vaccine. The largest longevity-focused trial, called PEARL, gave 114 adults aged 50 to 85 either a placebo or 5 or 10 milligrams of rapamycin once a week for 48 weeks. It missed its main goal: belly fat did not change. Women on the higher dose gained some lean mass and reported less pain. Serious side effects were similar across groups. The rapamycin used was a compounded form that is absorbed less well than the pharmacy version, so the real dose was lower than it sounds.

That is the whole of it. No trial has shown that rapamycin extends life or prevents disease in healthy people.
